brief demo of what QRQ CW morse code audio tones sound like using the FLAC AUDIO CODEC on Gstreamer Pipelines

NOTE: the QRQ CW AUDIO you are hearing, if what the FLAC encoded CW AUDIO sounds like after decoding it finally on the LAPTOP(Lubuntu 18.04)

the QRQ CW AUDIO stream starts on the LAPTOP goes to the PI over wired Ethernet, through routers & switches... then the PI re-encodes what it is receiving from the laptop and sends it right back to the laptop(basically a loopback formation on the PI)

HERE ARE THE Gstreamer SCRIPTS USED: "gst-launch-1.0"

NOTE: the FLAC CODEC on GSTREAMER has a default quality encoding setting of "5" ...so...just to see how well the CW NOTE audio quality could be encoded and decoded using FLAC at its lowest quality setting, a FLAC QUALITY SETTING of "zero" was used...and it turned out...at "ZERO", FLAC encodes faster with less strain on the CPU... and there was no degradation of the final received CW NOTE spectrum or waveshape when decoding it back to CW AUDIO
